Does anybody have any information like pin compatibility and >register (SW) compatibility? From the Philips SJA1000 product preview: "The SJA1000 is designed to be software and pin-compatible to the well-known Philips stand-alone CAN controller PCx82C200. (...) To keep the device software compatible by simultaneously supporting new features. two different modes of operation are implemented" There is a previously reserved bit in the clock divider register that you set to enable the new mode ("PeliCAN"). There is a couple of new registers which you use to control the new features, but all the old registers are still there. It seems to be fully pin compatible with the 82C200 and will be delivered in DIL28 or SO28 package. It has a 51-byte receive FIFO. There is still only one tx buffer, though (as far as I can see). The extensions in PeliCAN mode include: - CAN 2.0B - Error counters with read/write access - Programmable eror warning limit - Last Error Code Capture Register - Error Interrupt for each CAN bus error - Arbitration Lost Interrupt - Single Shot Transmission Option (no retransmission) - Listen Only Mode (no ACK, no active error flags) - Hot Plugging support (s/w driven bit rate detection) - Acceptance Filter Extension (4-byte code and mask) - Optional reception of own messages - Local self test --
